Description
Technical Field
The utility model relates to a diesel engine inner structure technical field specifically is a diesel engine bell housing structure.
Background
The power of the diesel engine for fire fighting is increasingly larger, the strengthening degree is also increasingly higher, and the structure is increasingly compact. For the V-shaped diesel engine, because the left column and the right column both need to be cooled, water from the water pump needs to be divided into two paths to cool the left side and the right side of the diesel oil, the external pipeline is generally arranged, the external pipeline is not only not attractive in appearance, but also not compact in structure, and the connecting places are more and are easy to have water leakage risks; in addition, two rows have all been arranged the booster about the diesel engine, and the booster needs to be lubricated, need get back to the oil pan behind the lubricated booster of lubricating oil, and general diesel engine all adopts the external mode of bellows, and inside the diesel engine organism of lubricating oil guide, the pipeline is very long, but also need arrange the oil gallery on the organism, can cause certain influence to organism structure, and the overall structure of diesel engine is comparatively complicated, and the processing equipment is very inconvenient.
Disclosure of Invention
Complicated to current diesel engine structure, it is unreasonable to set up, the difficult problem of processing equipment, the utility model provides a diesel engine bell housing structure, its simple structure, rationally distributed, processing equipment is convenient.
The technical scheme is as follows: the utility model provides a diesel engine flywheel shell structure, its includes the flywheel shell body, its characterized in that, it has two business turn over mouths the same with the water route about the diesel engine to open on the flywheel shell body, set up on the flywheel shell body wall and communicate two the water cavity of business turn over mouth, set up two oil gallery that communicate the crankcase on the flywheel shell body, set up on the flywheel shell body wall one end intercommunication oil gallery, the other end communicate the oil duct of booster.
The water cavity is an arc-shaped cavity, and a connecting flange is arranged on the water inlet and the water outlet;
the flywheel housing body is provided with at least two motor mounting holes, one of the motor mounting holes is provided with an electric motor, and the rest of the motor mounting holes are provided with an air motor or a mechanical energy storage motor;
and a manual turning piece is arranged on the edge of the flywheel shell body, and a wrench joint is arranged on the manual turning piece.
Adopt the utility model discloses a behind the structure, directly form water cavity and oil duct on the bell housing body wall, reduced external pipeline, simple structure, overall arrangement is compact reasonable, in the aspect of the processing equipment.

Detailed Description
See fig. 1, fig. 2, fig. 3, fig. 4, fig. 5, fig. 6 shows, a diesel engine flywheel shell structure, it includes flywheel shell body 1, it has two business turn over ports 2 the same with the water route about the diesel engine to open on the flywheel shell body 1, set up the water cavity 3 of two business turn over ports of intercommunication on the flywheel shell body 1 wall, water cavity 3 is the arc cavity, be provided with flange 4 on the business turn over port 2, link to each other with the water route through flange 4, can make the water route about the diesel engine can communicate with each other, set up two oil gallery 5 that communicate the crankcase on the flywheel shell body 1, set up one end intercommunication oil gallery 5 on the flywheel shell body 1 wall, oil duct 6 of the other end intercommunication supercharger, make the lubricating oil of supercharger can directly get back to in the crankcase. Three motor mounting holes 7 are formed in the flywheel housing body 1, only two of the three motor mounting holes 7 are used under ordinary conditions, an electric motor is mounted on one of the motor mounting holes 7, an air motor or a mechanical energy storage motor is mounted on the other one of the motor mounting holes 7, when the displacement of the diesel engine is more than 30L, the three motor mounting holes are needed, the electric motor is mounted on one of the motor mounting holes 7, and two mechanical energy storage motors are mounted on the other two motor mounting holes 7.
Manual barring spare is installed at 1 edge of bell housing body, manual barring spare is including the U-shaped piece 8 that is fixed in bell housing body 1, install the removable pin 9 on the U-shaped piece 8, first gear 10 is installed to removable pin 9 one end, wrench joint 11 is installed to the other end, install the second gear 12 with the flywheel meshing on the bell housing body 1, when needs barring, promote removable pin 9 and make first gear 10 and the meshing of second gear 12, use the spanner to rotate removable pin 9, through first gear 10, the barring operation of flywheel can be realized in the transmission of second gear 12, and is simple and convenient.
